There's a whole bunch of theories behind our ability to perceive colors and how it is made possible. According to science, color happens when light enters our eyes and is processed by the brain. Like that, we can tell red from yellow and blue from green. What we fail to tell is whether the red I see is identical to the one you see. We know about colorblind people, who are incapable of perceiving colors because of their weak receptors, and 'tetrachromats', who on the contrary, can see more colors than a normal person can - and we know this because these conditions are extreme. However, we're also unsure about whether the rest of the people are seeing the same colors or not, and it would be very difficult to be able to show evidence to this.

In the world, something is generally either alive, or not. But apparently, this is not the case with viruses. Scientists have detected some oddities going on in the behavior of viruses - leading some to believe they're living organisms, due to the fact that they can spread and multiply, and others that they're not alive, because of their absence of metabolic functioning. However, more research proved that viruses can also reproduce, show hints of evolution, and are even able to carry out its processes outside a living host. This leaves us with numerous doubts and unanswered questions to viruses' state of being.

If only we knew the answer to this. Well, science has made an attempt at answering it, by providing actual biological evidence of what happens in our cells during this process. Basically, as we grow older, our muscles tend to lose mass, our tissues increase in rigidity and stiffness, and the new cells produced by our body lose their efficiency at absorbing nutrients and getting rid of waste. This may all be true, but it still doesn't tell us WHY it happens. So far, we've had various theories that have tried to find an answer to it, claiming that aging is a by-product of the body's waste materials, or that it's the result of external factors such as UV-rays, or even because it's in our genetics. The bad news is - none of these have been proven yet.
Another curiosity about aging is the fact that people age at different rates - what might be the explanation for that? Is it perhaps in our genes too? Whatever the answers may be, no one is anywhere close to knowing them.

Migraines are not infections, diseases or conditions. They are very often kinds of aches, which turn out to be stronger than headaches, and come with several other symptoms such as nausea, blurred vision,  painful sensitivity to stimuli, vomiting, and in some cases even loss of consciousness. These symptoms vary from one person to another, and what they are triggered by is something many people still wonder about. Being exposed to changes in weather, certain smells or foods, or having undergone physical exertion, are said to be some of the most evident and possible causes. Some even say that the tendency of having migraines can be inherited through our genes, and  that people who are more prone to getting them have certain parts in their brains that are more sensitive than others. However, there's no concrete proof for these assertions so far.
 
10. Why do allergies come and go?



Allergies can be difficult to live with, but some people find that theirs have unexpectedly disappeared, while others find they're suddenly suffering from one they've never had. The way this happens is a curious case indeed. Although it is scientifically possible for this to happen, we are unsure of the reason behind it. Bizarrely enough, 20% of children who have a peanut allergy lose their sensitivity as they grow older, and 80% of children who have a milk allergy lose it too by the time they reach their teens. What's more,  it has been observed that the children of the present have a much larger chance of outgrowing their allergies than the children of past generations. All these facts do nothing more than stump us even more about the mysteries of this world.
